In general, the GPU codes for CFD applications are written in traditional languages such as Fortran or C++ [1]}, [2]}, [3]}, [4]}. In recent years, modern languages such as Python [5]}, Julia [6]}, Regent [7]}, Chapel [8]} have steadily risen in the domain of scientific computing. These languages are known to be architecture independent with the added advantage of easy code maintenance and readability. Recently, Python has been used to develop an industry standard CFD code, PyFR for compressible flows [9]}. To the best of our knowledge, a rigorous investigation and comparison of the performance of GPU codes for CFD written in both traditional and modern languages are not yet pursued.
